Description

FIELD OF THE INVENTION



[0001] The present invention relates to substituted heterocyclic compounds, and compositions thereof as well as such compounds and compositions for use as hypoxia mimetics. This invention further discloses methods of increasing HIF (Hypoxia Inducible Factor) levels or activity in a subject or treating a condition associated with HIF levels or activity such as ischemia, anemia, wound healing, auto-transplantation, allo-transplantation, xenotransplantation, systemic high blood pressure, thalassemia, diabetes, cancer, and an inflammatory disorder.

BACKGROUND OF THE INVENTION



[0002] The cellular transcription factor HIF (Hypoxia Inducible Factor) occupies a central position in oxygen homeostasis in a wide range of organisms and is a key regulator of responses to hypoxia. The genes regulated by HIF transcriptional activity can play critical roles in angiogenesis, erythropoiesis, hemoglobin F production, energy metabolism, inflammation, vasomotor function, apoptosis and cellular proliferation. HIF can also play a role in cancer, in which it is commonly upregulated, and in the pathophysiological responses to ischemia and hypoxia.

[0003] The HIF transcriptional complex comprises an heterodimer: HIF is a constitutive nuclear protein that dimerizes with oxygen-regulated HIF subunits. Oxygen regulation occurs through hydroxylation of the HIF subunits, which are then rapidly destroyed by the proteasome. In oxygenated cells, the von Hippel-Lindau tumor suppressor protein (pVHL) binds to hydroxylated HIF-subunits, thereby promoting their ubiquitin dependent proteolysis. This process is suppressed under hypoxic conditions, stabilizing HIF and promoting transcriptional activation by the HIF complex.

[0004] Hydroxylation of HIF-subunits can occur on proline and asparagine residues and can be mediated by a family of 2-oxoglutarate dependent enzymes. This family includes the HIF prolyl hydroxylase isozymes (PHDs), which hydroxylate Pro 402 and Pro 564 of human HIF1, as well as Factor Inhibiting HIF (FIH), which hydroxylates Asn 803 of human HIF1. Inhibition of FIH or the PHDs leads to HIF stabilization and transcriptional activation. See, e.g., Schofield and Ratcliffe, Nature Rev. Mol. Cell Biol., Vol5, pages 343-354 (2004).

[0005] WO 2007/103905 describes bicyclic heteroaromatic N-substituted glycine derivatives, which are described to be antagonists of HIF prolyl hydroxylases and are described to be useful for treating diseases benefiting from the inhibition of this enzyme, anemia being one example.

[0006] WO 2007/025169 describes HIF-1 inhibitors and methods of use thereof.

[0007] Thus, new or improved agents that modulate (such as increasing HIF levels or activity) HIF are continually needed for developing new and more effective pharmaceuticals to treat HIF-associated conditions or diseases or disorders, such as ischemia, anemia, wound healing, auto-transplantation, allo-transplantation, xenotransplantation, systemic high blood pressure, thalassemia, diabetes, cancer, and an inflammatory disorder, to name a few. In discovering new or improved agents that modulate HIF level or activity, it is also desirable but not required to discover agents with improved chemical or biological properties such as solubility, bioavailability, pharmacokinetics, pharmacodynamics, toxicity and/or less side effects such as less cardiovascular side effects. The compounds, compositions, and methods described herein are directed toward these needs and other ends.

SUMMARY OF THE INVENTION



[0008] The present invention provides, inter alia, compounds of Formula I:

or a pharmaceutically acceptable salt thereof, a solvate thereof or a chelate thereof as defined in claim 1.

[0009] The present invention further provides pharmaceutical compositions as defined in claim 58. The present invention further provides use of the compounds of Formula I in the manufacture of a medicament for the treatment of a disease, disorder, or condition as defined in claim 62.

[0010] Further embodiments are set forth in the appended dependent claims.

[0141] 



[0142] Reagent 1 (42 g, 33.6 mmol) was dissolved in 200 mL of AC2O with addition of 1 mL of H3PO4, and was heated at 50°C. After its completion, the reaction mixture was cooled to room temperature, and 500 mL of water was then added in and stirred at 50°C until hydrolyzation is complete. The reaction mixture was then cooled to 0 °C and filtered. The resulting solid, Compound 2, was further dried (47 g).

[0143] Compound 2 (25.9 g, 100 mmol) and 1-Hydroxybenzotriazole anhydrous (HOBt, 13.5 g) was dissolved in 400 mL of THF. Dicyclohexylcarbodiimide (DCC, 20.9 g) was gradually added in at 0 °C and stirred over night at a temperature below 10°C. The reaction mixture was filtered and the Filtrate A was collected. 13.2 g (100 mmol) of dimethyl malonate was dissolved in 800 mL of THF first, then 7.2 g sodium hydride (70% dispersion) was added in. Filtrate A was added while stirred and left to react for 2 hours at room temperature. After THF removed by vacuum distillation, 400 mL of methanol and 400 mL of 10% HCl were added and stirred over night. After filtration, the resulting solid was washed with 400 mL of methanol and dried, yielding 14 g of Compound 3.

The resulting solution was heated to 80°C under nitrogen gas overnight. After its completion, the reaction mixture was cooled to room temperature. 100L of water and 100mL of ethyl acetate were added and stirred. The organic layer was retained and washed twice more by water, followed by quickly passing through a silicon gel column to remove solvent. 5mL of dichloromethane and 5mL of trifluoroacetic acid were then added and stirred at room temperature for 4 hrs. After its completion, the reaction mixture was evaporated in vacuo. The resulting product was further purified by recrystallization using CH3OH-THF to arrive at the title compound 6, with the LC-MS [M-H]- m/z 338, and 1H-NMR (300 MHz, (CD3)2SO) δ 13.01 (br s, 1H), 9.55 (br s, 1H), 8.05 (d, 1H, J = 9.0 Hz), 7.85 (d, 1H, J = 9.0 Hz), 7.83 (t, 1H, J =7.5 Hz), 7.82 (dd, 2H, J = 7.5, 7.5 Hz), 7.54 (dd, 2H, J = 7.5, 1.5 Hz), 7.46 (s, 1H), 4.14 (d, 2H, J = 6.0 Hz).
